Hi stephan,
I have used XAMPP as local web server. I took the seven steps successfully of the tutorial but something is wrong when i try to login.
I think there is a problem with some link (the way of working XAMPP when you put localhost in your browser)
I copied the the folder /opn2/html in /opt/lampp/htdocs
I browser with http://localhost/html/install.php
I took the seven step but with some doubts
URL: http://localhost/htdocs ?
Physical path: /opt/lampp/htdocs/html ?

When i try login i saw the page without any elements just text plain and the next message when i put my login
The requested URL /system/user/index.php was not found on this server.

Is a question of a little link but i don't see it

José

URL: http://localhost/htdocs ? => http://localhost/html
